Disclaimer I have only tested this while working on Clang, but I assume
it works for the entire LLVM project.
I have enabled shared libraries in CMake. Then I add the following lines
to the CMakeLists.txt, for example clang/lib/Parse/CMakeLists.txt
COMPILE_FLAGS "-O0 -g"
Then rebuild the clangParse target and have the debug symbols available.
Hope this helps.
